In the present paper, the fluorescence spectral curves of J-aggregates of two kinds of anionic-cationic cyanine dyes adsorbed on AgIBr cubic microcrystals were measured by using fluorescence spectroscopy, and compared with the sensitivity characteristic of anionic-cationic cyanine dyes. The results show that the peaks of fluorescence spectral curves of anionic-cationic cyanine dyes were lower than that of anionic and cationic cyanine dyes, and the higher sensitivity efficiency was due to the fact that more electrons transfer to the surface of AgIBr microcrystal.
在本文中，利用荧光光谱法测量了吸附在立方溴碘化银微晶上的两种阴阳离子菁染料J-聚集体的荧光光谱曲线，并与阴阳离子菁染料的感光度特性进行了比较。结果表明，阴阳离子菁染料的荧光光谱曲线峰值低于阴离子和阳离子菁染料，且感光度更高是由于更多电子转移到溴碘化银微晶表面这一事实。
